Front-Panel Key Reference
File
Key Access: File, Load, Type
State
Displays all state files you may wish to
load (.STA). Loading a state restores
most settings to the previously saved
values.
Key Access:
File, Load, Type
Trace
Displays all trace files (.TRC) you may
wish to load. Traces can be loaded
individually or as a group. When a
trace is loaded, the state that existed
when that trace was saved is loaded
along with the trace. Also, the loaded
trace is placed in view mode.
Key Access:
File, Load, Type
NOTE If you wish to compare two saved traces, place traces in view mode
before saving them. This prevents the trace from being rewritten based
on a state change from subsequent loads.
Limits Displays all limits files you may wish to
load to determine whether a trace has
exceeded preset specifications (.LIM).
Limit sets can hold up to 200 points.
Limits can only be loaded individually.
Key Access:
File, Load, Type
NOTE When loading Limits files, be sure you have selected the appropriate
X-Axis Units: frequency or time (Display, Limits, X Axis Units). If you are
in time X-Axis Units, and you load frequency limits, all current limit
line data will be erased and the analyzer will switch to frequency units.
The reverse of the this situation also holds true.
Corrections Displays all corrections files you may
wish to load (.CBL, .ANT, .OTH, .AMP).
Corrections provide a way to adjust the
trace display for preset gain factors
(such as for cable loss). A correction set
may hold up to 200 points.

Signal List
Displays all signal list files (.LST) you
may wish to load and allows you to load
a selected signal list. The signal list
files contain a list of signals which
include the frequency and measured
amplitudes for each signal.
